NVIDIA Direct Attached Copper Cables

NVIDIA LinkX Direct Attached Copper (DAC) cables and Splitter cables make it easy to connect 10, 25, 50 and 100Gb/s servers/storage and appliances using network adapters to 40G & 100G Top-Of-Rack (TOR) switches. DACs are widely used in data centers to connect servers to the Top Of the Rack (TOR) switch because they are passive, consume zero power and have the lowest latency. DAC cables are the lowest cost way to create 100G links.  NVIDIA offers a wide range of products for 0.5m to 7m reaches and in SFP and QSFP form factors.

LinkX certified cables are 100% tested in actual NVIDIA systems to ensure optimal signal integrity and the best end-to-end performance. NVIDIA DAC cables are designed for use in super computers that have very stringent requirements. IEEE standards require 1E-12 Bit Error Ratio (BER), but all NVIDIA cables are tested to 1E-15 which is 1,000 times fewer bit errors than competitors. NVIDIA passive copper cables offer trouble free installation, long-term reliable operation and they work with 3rd-party switches and adapters.

NVIDIA LinkX Direct Attached Copper (DAC) cables are available in a variety of configurations, from 10G to 100G, including

  • Ethernet 10G
  • Ethernet 25G
  • Ethernet 40G
  • Ethernet 100G
  • Ethernet 40G with 4 x 10G
  • Ethernet 100G with 4 x 25G
  • Ethernet 100G with 2 x 50G
